Chemically Modified Carbon and Carbon Nanotubes (CNTs)


Although nano electrochemistry is no longer an area of active interest to the group, we maintain our expertise in chemically modifying graphitic carbon (graphite, glassy carbon, CNTs and C60 fullerenes) with a whole host of organic molecules, metal nanoparticles, organometallic complexes and biomolecules. These novel materials are characterised using several electrochemical and surface analysis techniques including X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM) and various electron microscopic methods (SEM/HRTEM/EDAX). The routes we choose to follow in order to chemically link modifiers to the surface include the use of radical, electrophilic, nucleophilic synthetic pathways and physical or electrostatic surface interactions.

Once the fundamental properties and characteristics of each modified material are understood we then seek to apply these for chemical sensing, catalysis and other relevant applications to solve “real world” problems. This aspect of my research is strongly inter-linked to many other areas we are currently actively working on.
